Description

Die vorliegende Erfindung betrifft eine Prüfeinrichtung für mit Lichtwellenleitern bestückte Stecker gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a test device for equipped with optical fibers Plug according to the preamble of claim 1.

Eine derartige Prüfeinrichtung ist aus der DE 297 16 026 bekannt.Such a test device is known from DE 297 16 026.

Darin ist beschrieben, daß der im wesentlichen durch einen Lichtwellenleiter gebildete Prüfstift über einen Lichtwellenleiter an einen Empfänger angeschlossen ist. Dieser vergleicht die empfangenen Signale mit einem definierten Wert, wobei die Signale von einem Sender ausgehen, der am anderen Ende des Lichtwellenleiters angeschlossen ist, der in den Stecker eingesteckt und mit diesem verbunden ist und dessen einwandfreie Durchgängigkeit ermittelt werden soll.It describes that the essentially formed by an optical waveguide Test pin is connected to a receiver via an optical fiber. This compares the received signals with a defined value, the signals from a transmitter that is connected to the other end of the optical fiber, which is plugged into and connected to the plug and its flawless Continuity should be determined.

In jedem Fall ist ein vom Prüfstift separater Empfänger und Sender erforderlich, die beide mit einer Auswerteelektronik gekoppelt sind.In any case, a receiver and transmitter separate from the test pin is required both are coupled to evaluation electronics.

Nachteilig ist jedoch, daß durch den Lichtwellenleiter, der den Prüfstift mit dem Empfänger bzw. dem Sender verbindet, durchaus Verluste auftreten, die beispielsweise in einer Beschädigung des Lichtwellenleiters zwischen dem Prüfstift und dem Empfänger oder dem Sender begründet sein können. The disadvantage, however, is that the fiber optic cable connects the test pin with the receiver or connects the transmitter, losses occur, for example, in damage to the optical fiber between the test pin and the receiver or the sender may be justified.

Zumindest besteht die Gefahr einer Beschädigung des Lichtwellenleiters bei einer Montage bzw. Demontage des Prüfstiftes.At least there is a risk of damage to the optical fiber in a Assembly or disassembly of the test pin.

Darüber hinaus ist ein Auswechseln des Senders oder Empfängers, was aus unterschiedlichsten Gründen erforderlich sein kann, relativ aufwendig, da hierzu die gesamte Vorrichtung soweit zu zerlegen ist, daß ein freier Zugriff zu den entsprechenden Teilen möglich ist.In addition, changing the transmitter or receiver is different Reasons may be necessary, relatively expensive, because the entire The device must be dismantled to such an extent that there is free access to the corresponding Sharing is possible.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Prüfeinrichtung der gattungsgemäßen Art so weiter zu entwickeln, daß ihre Betriebssicherheit erhöht wird und die Betriebskosten aufgrund der Möglichkeit, die Wartung und Instandsetzung einfacher und schneller durchführen zu können, gesenkt werden. Diese Aufgabe wird durch eine Prüfeinrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist.The present invention is therefore based on the object of a test device to further develop the generic type so that its operational safety increases and operating costs due to the possibility of maintenance and repair to be carried out more easily and quickly. This task is solved by a test device having the features of claim 1.

Eine solche Prüfeinrichtung hat zunächst einmal den Vorteil, daß kein zusätzlicher Lichtwellenleiter vom Prüfstift zum Empfänger bzw. zum Sender erforderlich ist.Such a test device has the advantage that no additional Optical fiber from the test pin to the receiver or transmitter is required.

Hierdurch werden natürlich die durch den Einsatz eines Lichtwellenleiters sich möglicherweise ergebenden Probleme hinsichtlich der Betriebssicherheit beispielsweise durch Beschädigung vollständig vermieden. So sind daraus resultierende Fehlermeldungen, wie sie beispielsweise auftreten, wenn ein Lichtwellenleiter geknickt ist, ausgeschlossen.This, of course, may result in the use of an optical fiber resulting operational safety issues, for example completely avoided by damage. The resulting error messages are as they occur, for example, when an optical fiber is kinked, excluded.

In der Praxis bedeutet dies, daß, wenn ein Fehler ermittelt wird, dieser ausschließlich im Lichtwellenleiter vorliegt, der an dem Stecker angeschlossen ist.In practice, this means that if an error is found, it is exclusive is present in the optical fiber that is connected to the connector.

Insoweit ergibt sich auch eine wesentliche Verbesserung der Prüfsicherheit.In this respect, there is also a significant improvement in test reliability.

Durch die räumliche Trennung zwischen dem Empfänger und/oder Sender und der Auswertelektronik kann nun nun ein defekter Empfänger oder Sender leicht ausgewechselt werden, ohne daß die gesamte Prüfeinrichtung zerlegt werden muß.Due to the spatial separation between the receiver and / or transmitter and the Evaluation electronics can now easily replace a defective receiver or transmitter without having to disassemble the entire test facility.

Zu dieser im Bedarfsfall sehr leichten Auswechselbarkeit des Empfängers oder Senders trägt auch ein weiterer vorteilhafter Gedanke der Erfindung bei, wonach der Prüfkopf abnehmbar am Prüfstift im übrigen befestigt ist, beispielsweise durch Verschrauben. For this very easy interchangeability of the receiver or transmitter if necessary also contributes another advantageous idea of the invention, according to which the test head is detachably attached to the test pin, for example by screwing.

Der Prüfkopf ist von der Steckeraufnahme her leicht zugänglich und ohne weiteres abzunehmen und auszutauschen, wodurch sich natürlich erhebliche Montagevorteile ergeben, die insbesondere durch kürzere Betriebsunterbrechungszeiten entstehen.The test head is easily accessible from the connector receptacle and is easy to use to remove and replace, which of course has considerable assembly advantages result in particular from shorter business interruption times.

Sowohl der Empfänger wie auch der Sender bestehen in an sich bekannter Weise aus Dioden, die als handelsübliche Bauteile äußerst preiswert angeboten werden. Deren Beschaffungskosten stehen in keinem Verhältnis zu den bislang hohen Montagekosten.Both the receiver and the transmitter consist in a manner known per se Diodes that are offered as commercially available components at extremely low prices. Their Procurement costs are disproportionate to the previously high assembly costs.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnung beschrieben.An embodiment of the invention is described below with reference to the accompanying Drawing described.

Die

The
Figure 1
shows a detail of the test device according to the invention in a sectional side view.

In der Figur ist ein Prüfstift 1 dargestellt, der eine Hülse 4 aufweist, die in einem nicht dargestellten Kupplungsteil festgelegt ist.In the figure, a test pin 1 is shown, which has a sleeve 4, which is not in one shown coupling part is fixed.

In die Hülse 4 ist eine Gewindebuchse 10 eingeschraubt, wobei an der Gewindebuchse 10 ein Außen- und in der Hülse 4 ein Innengewinde 6, 7 vorgesehen sind.A threaded bushing 10 is screwed into the sleeve 4, on the threaded bushing 10 an external and in the sleeve 4 an internal thread 6, 7 are provided.

In der Gewindebuchse 10 ist eine Buchse 9 achsverschieblich gelagert, in der ein Prüfkopf 2 mit einer Empfängerdiode 3 angeordnet ist. Anstelle einer Empfängerdiode 3 kann auch eine Senderdiode vorgesehen sein. Dabei ist die Empfängerdiode 3 an einem Kolben 8 angeschlossen, der in der Buchse 9 befestigt ist.In the threaded bush 10, a bush 9 is axially displaceable, in which a test head 2 is arranged with a receiver diode 3. Instead of a receiver diode 3 a transmitter diode can also be provided. The receiver diode 3 is on one Piston 8 connected, which is fixed in the socket 9.

An der dem Prüfkopf 2 gegenüberliegenden Stirnseite stützt sich die Buchse 9 an einen Kontaktstift 11 ab, der federbelastet und axial verschiebbar in einer Kontakthülse 5 geführt ist, die fest mit der Hülse 4 verbunden ist.On the end face opposite the test head 2, the socket 9 is supported on one Contact pin 11, which is spring-loaded and axially displaceable in a contact sleeve 5 is guided, which is firmly connected to the sleeve 4.

Dabei wirkt die Federkraft in Richtung der Buchse 9, so daß ein zu prüfender Stecker nur unter Herunterdrücken des Prüfkopfes 2 gegen diese Federkraft in die nicht dargestellte Steckeraufnahme einsetzbar ist. The spring force acts in the direction of the socket 9, so that a connector to be tested only by pressing the test head 2 against this spring force into the not shown Plug receptacle can be used.

An die Kontakthülse 5 ist eine Leitung 12 angeschlossen, die mit einer Auswerteelektronik in Verbindung steht.A line 12 is connected to the contact sleeve 5 and is equipped with an evaluation electronics communicates.

Um den Prüfkopf 2 auszuwechseln, ist die Gewindebuchse 10 aus der Hülse 4 herauszuschrauben, wobei zweckmäßigerweise die Gewindebuchse 10 oberseitig eine Werkzeugaufnahme, beispielsweise in Form eines Sechskantes, aufweist, so daß ein Einsetzen von oben her bzw. ein Herausdrehen ohne weiteres möglich ist. In order to replace the test head 2, the threaded bushing 10 must be unscrewed from the sleeve 4, the threaded bushing 10 expediently has a tool holder on the top, for example in the form of a hexagon, so that an insertion from above or unscrewing is easily possible.
